Distant quasar J0439+1634 explored in X-rays
Using ESA's XMM-Newton spacecraft, an international team of astronomers has conducted X-ray observations of the most distant known gravitationally lensed quasar—J0439+1634. Results of the study, published December 20 on the arXiv pre-print server,.....»»
Improvisation pedagogy supports the social skills of all kinds of learners
In her doctoral research, Eeva Siljamäki has explored the possibilities of improvisation for music education. Her aim has been to increase understanding of how playful collaborative improvisation can enhance not only musical learning but also the qu.....»»
FAST is promising in interplanetary scintillation observation
The radio signal from a distant compact radio source is scattered by the density inhomogeneities of the solar wind, and consequently a random diffraction pattern is observed on the Earth......»»
Researchers develop better ways to culture living heart cells on the International Space Station
As part of preparing for an experiment aboard the International Space Station, researchers explored new ways to culture living heart cells for microgravity research. They found that cryopreservation, a process of storing cells at -80°C, makes it eas.....»»
Best practices for researching with child language learners explored in new book
The ethical practices, dilemmas and challenges of classroom research involving child language learners are the focus of a new book edited by Dr. Annamaria Pinter of the University of Warwick's Department of Applied Linguistics and Dr. Harry Kuchah of.....»»
Probing deeper into origins of cosmic rays
Cosmic rays are high-energy atomic particles continually bombarding Earth's surface at nearly the speed of light. Our planet's magnetic field shields the surface from most of the radiation generated by these particles. Still, cosmic rays can cause el.....»»
New detector finds gamma rays from surprising cosmic sources
Astrophysicist Cao Zhen opens a steel hatch on a windswept Tibetan Plateau and climbs down a ladder into inky darkness. His flashlight picks out a boat floating on a pool of purified water above thousands of glittering orbs the size of beachballs......»»
Hubble tracks down fast radio bursts to galaxies" spiral arms
Astronomers using NASA's Hubble Space Telescope have traced the locations of five brief, powerful radio blasts to the spiral arms of five distant galaxies......»»
Google is opening a retail store in New York this summer
Google has explored storefronts for a while now. Here’s a pop-up in Manhattan’s SoHo district that we took a trip to some four+ years back. But the company’s own branded retail experience has been fairly limited — unsurprising, given that.....»»
Machines can"t "personalize" education, only people can
In the past year, COVID-19 abruptly disrupted schooling, and forced the question of how much kindergarten to Grade 12 education should or will rely on online teaching in the near and distant future. Education has taken a decided technological turn in.....»»
Researcher describes four new species of sponge that lay undiscovered in plain sight
The ocean is a big place with many deep, dark mysteries. Humans have mapped no more than 20% of the sea, and explored less. Even the kelp forests of Southern California—among the best studied patches of ocean on the planet—hide species not yet de.....»»
Beyond our solar system, Voyager 1 picks up the hum of interstellar gas
The two most distant man-made objects in the universe are the Voyager probes, launched in the 1970s. Now, Voyager 1 has found a hum of interstellar gas......»»
Cancer has ripple effect on distant tissues
A new study with zebrafish shows that a deadly form of skin cancer -- melanoma -- alters the metabolism of healthy tissues elsewhere in the body. The research suggests that these other tissues could potentially be targeted to help treat cancer......»»
Non-linear optics meets X-rays
The recent advent of femtosecond X-ray sources offers unprecedented opportunities for structural and dynamical studies. It requires, however, manipulating spectral properties, as commonly done by non-linear optics at visible/infrared wavelengths. Her.....»»
Artificial intelligence tool uses chest X-ray to differentiate worst cases of COVID-19
Trained to see patterns by analyzing thousands of chest X-rays, a computer program predicted with up to 80 percent accuracy which COVID-19 patients would develop life-threatening complications......»»
Of mice and spacemen: Understanding muscle wasting at the molecular level
Skeletal muscles undergo atrophy, or wasting, under conditions of reduced gravity, such as during spaceflight. Researchers explored the effects of microgravity and artificial gravity (1 g) on mice housed at the International Space Station for 35 days.....»»
Shaken, not stirred: Ultrafast skyrmion reshuffling
Smaller, faster, more energy-efficient: future requirements to computing and data storage are hard to fulfill and alternative concepts are continuously explored. Small magnetic textures, so-called skyrmions, may become an ingredient in novel memory a.....»»
Voyager 1 Detects Plasma "Hum"
Obipale shares a report from Phys.Org: Voyager 1 -- one of two sibling NASA spacecraft launched 44 years ago and now the most distant human-made object in space -- still works and zooms toward infinity. The craft has long since zipped past the edge o.....»»
Xiaomi patent reveals an under-display rotating camera for selfies and rear-facing photography
Phones such as the Asus Zenfone 7 Pro have previously explored the idea of using powerful rear-facing cameras that can be flipped around for taking selfies. While that implementation with its motorized hinge causes the phone to transform physically o.....»»
In the emptiness of space, Voyager 1 detects plasma "hum"
Voyager 1—one of two sibling NASA spacecraft launched 44 years ago and now the most distant human-made object in space—still works and zooms toward infinity......»»
A new way to look at the inner workings of tiny magnets
Researchers from NTNU are shedding light on magnetic materials at small scales by creating movies with the help of some extremely bright X-rays......»»
